Several law enforcement agencies raided the Jackson County jail early Friday looking for illegal contraband.

Jackson County Sheriff Sgt. John Payne says the raid was planned after cellphones were found on inmates recently.

He says the goal was to find any more cellphones as well as contraband such as homemade weapons and narcotics.

The sheriff's department plans to conduct more jail sweeps in the future. Payne says the raids are intended to keep the jail safe for inmates and jail employees.

No information was released on whether more contraband was found during Friday's operation.

Besides Jackson County, other agencies participating in the raid included the FBI, Kansas City police and several other metro-area police departments.
